Broken twitter backend, how to repair?
 

I got fresh n950 with 40.212.17-2 , enabled n9 repo to install skype, then a notice appeared that twitter update is available. I installed it (previous versions of n9 twitter worked fine), then I installed 40.212.21-3 and at some point twitter app got broken. I still wonder how was it possible to update twitter alone as apt shows it is part of PR metapackage, but that's it: now I have twitter 1.3.50+0m8 and it fails with "xsession/mtwitter main process terminated with status 1".

Any ideas how to fix it?
